Loss-of-function variants in CSDE1 have been strongly linked to neuropsychiatric disorders, yet the precise role of CSDE1 in neurogenesis remains elusive. In this study, we demonstrate that knockout of Csde1 during cortical development in mice results in impaired neural progenitor proliferation, leading to abnormal cortical lamination and embryonic lethality. Transcriptomic analysis revealed that Csde1 upregulates the transcription of genes involved in the cell cycle network. Applying a dual thymidine-labelling approach, we further revealed prolonged cell cycle durations of neuronal progenitors in Csde1-knockout mice, with a notable extension of the G1 phase. Intersection with CLIP-seq data demonstrated that Csde1 binds to the 3' untranslated region (UTR) of mRNA transcripts encoding cell cycle genes. Particularly, we uncovered that Csde1 directly binds to the 3' UTR of mRNA transcripts encoding Cdk6, a pivotal gene in regulating the transition from the G1 to S phases of the cell cycle, thereby maintaining its stability. Collectively, this study elucidates Csde1 as a novel regulator of Cdk6, sheds new light on its critical roles in orchestrating brain development, and underscores how mutations in Csde1 may contribute to the pathogenesis of neuropsychiatric disorders.

Medical supply is a key resource for responding to public health emergencies and maintaining people's lives and health. As the medical equipment management department, the medical devices department is mainly responsible for the procurement, supply, technical support, management and coordination of medical equipment and medical consumables, playing an important role in epidemic prevention and control. Through the analysis of the expansion cases of designated hospitals, the experience of emergency management of medical equipment has been accumulated, which has strong practicability and replicability.

Objective To explore the needs of community pharmacy services in elderly hypertensive patients in the community, especially empty-nest elderly patients. Methods Elderly hypertensive patients living in Ouyang street were randomly selected and divided into empty-nest and non-empty-nest groups by cluster random sampling method. The basic information of the respondents, the frequency of hypertension monitoring, the taking of hypertensive drugs, and the taking of other drugs were compared and analyzed. Results In term of “blood pressure monitoring frequency”, the daily pressure measurement of the empty-nest group and the non-empty-nest group accounted for 33.6% and 19.3%, respectively. There was significant difference between the two groups (P<0.05).In term of “the varieties of hypertension drugs” and taking 3 kinds of hypertension drugs at the same times, the empty-nest group accounted for 28.8% and the non-empty-nest group accounted for 16.7%, and the difference between the two groups was significant (P<0.05)；In term of “the varieties of drugs” and taking 1-2 kinds of Chinese patent drugs at the same time, the empty-nest group accounted for 39.6% and the non-empty-nest group accounted for 26.0% , and the difference between the two groups was significant (P<0.05)。Conclusion Community elderly patients with hypertension, especially empty-nest elderly patients have an urgent need for community pharmacy services，Community pharmacy services personnel should provide personalized and targeted medication education and guidance to elderly patients, especially empty-nest elderly patients, to promote the rational drug use in elderly patients.

Wolfiporia cocos (F. A. Wolf) has been praised as a food delicacy and medicine for cen-turies in China. Here, we present the genome and transcriptome of the Chinese strain CGMCC5.78 of W. cocos. High-confidence functional prediction was made for 9277 genes among the 10,908 total predicted gene models in the W. cocos genome. Up to 2838 differentially expressed genes (DEGs) were identified to be related to sclerotial development by comparing the transcriptomes of mycelial and sclerotial tissues. These DEGs are involved in mating processes, differentiation of fruiting body tissues, and metabolic pathways. A number of genes encoding enzymes and regulatory factors related to polysaccharide and triterpenoid production were strikingly regulated. A potential triter-penoid gene cluster including the signature lanosterol synthase (LSS) gene and its modified compo-nents were annotated. In addition, five nonribosomal peptide synthase (NRPS)-like gene clusters, eight polyketide synthase (PKS) gene clusters, and 15 terpene gene clusters were discovered in the genome. The differential expression of the velevt family proteins, transcription factors,carbohydrate-active enzymes, and signaling components indicated their essential roles in the regu-lation of fungal development and secondary metabolism in W. cocos. These genomic and transcrip-tomic resources will be valuable for further investigations of the molecular mechanisms controlling sclerotial formation and for its improved medicinal applications.

We cloned and analyzed the two genes of the 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase (HDR) gene family from Huperzia serrate. The two transcripts coding HDR, named HsHDR1 and HsHDR2, were discovered in the transcriptome dataset of H. serrate and were cloned by reverse transcription-polymerase chain reaction (RT-PCR). The physicochemical properties, protein domains, protein secondary structure, and 3D structure of the putative HsHDR1 and HsHDR2 proteins were analyzed. The full-length cDNA of the HsHDR1 gene contained 1431 bp encoding a putative protein with 476 amino acids, whereas the HsHDR2 gene contained 1428 bp encoding a putative protein of 475 amino acids. These two proteins contained the conserved domain of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase (PF02401), but without the transmembrane region and signal peptide. The most abundant expression of HsHDR1 and HsHDR2 was detected in H. serrate roots, followed by the stems and leaves. Our results provide a foundation for exploring the function of HsHDR1 and HsHDR2 in terpenoid and sterol biosynthesis in Huperziaceae plants.
